• Distribution of Relaxation Times
• Nuclear Quadrupole Resonance
• Surface Phenomena

The results of the experimental study of the influence of the environment surrounding the surface of the crystallites of a KClO3 powder on the distribution of the spin-spin and spin-lattice relaxation times for Cl-35 nuclear quadrupole resonance are described. It was found that the distributions of the spin-lattice relaxation times are unimodal and distributions of the spin-spin relaxation times are bimodal for all samples we studied. T-1 - T-2 and T-1 rho - T-2 correlations by means of the two-dimensional (2D) inverse Laplace transform are obtained. The efficiency of the method for the study of surface phenomena in solids is demonstrated.
